          At or before 11:00 a.m. (Toronto time) three Banking Days prior to the expiration of each Interest Period of each Libor Loan, the Borrower shall, unless it has delivered a Conversion Notice pursuant to Section 2.8 and/or a Repayment Notice pursuant to Section 2.15 (together with a Rollover Notice if a portion only is to be converted or repaid; provided that a portion of a Libor Loan may be continued only if the portion which is to remain outstanding is equal to or exceeds the minimum amount required hereunder for Drawdowns of Libor Loans) with respect to the aggregate amount of such Loan, deliver a Rollover Notice to the Agent selecting the next Interest Period applicable to the Libor Loan, which new Interest Period shall commence on and include the last day of such prior Interest Period. If the Borrower fails to deliver a Rollover Notice to the Agent as provided in this Section, the Borrower shall be deemed to have given a Conversion Notice to the Agent electing to convert the entire amount of the maturing Libor Loan into a U.S. Base Rate Loan.

2.10 Rollovers and Conversions not Repayments

          Any amount converted shall be a Loan of the type converted to upon such Conversion taking place, and any amount rolled over shall continue to be the same type of Loan under the Credit Facility as before the Rollover, but such Conversion or Rollover (to the extent of the amount converted or rolled over) shall not of itself (notwithstanding the repayment referred to in the definition of Conversion) constitute a repayment or a fresh utilization of any part of the amount available under the Credit Facility.

2.11

Agent’s Obligations with Respect to Canadian Prime Rate Loans, U.S. Base Rate Loans and Libor Loans

          Upon receipt of a Drawdown Notice, Rollover Notice or Conversion Notice with respect to a Canadian Prime Rate Loan, U.S. Base Rate Loan or Libor Loan, the Agent shall forthwith notify the Lenders of the requested type of Loan, the proposed Drawdown Date, Rollover Date or Conversion Date, each Lender’s Rateable Portion of such Loan and, if applicable, the account of the Agent to which each Lender’s Rateable Portion is to be credited.

2.12

Lenders’ and Agent’s Obligations with Respect to Canadian Prime Rate Loans, U.S. Base Rate Loans and Libor Loans

          Each Lender shall, for same day value on the Drawdown Date specified by the Borrower in a Drawdown Notice with respect to a Canadian Prime Rate Loan, a U.S. Base Rate Loan or a Libor Loan, credit the Agent’s Account with such Lender’s Rateable Portion of each such requested Loan and for same day value on the same date the Agent shall pay to the Borrower the full amount of the amounts so credited in accordance with any payment instructions set forth in the applicable Drawdown Notice.

2.13 Irrevocability

          A Drawdown Notice, Rollover Notice, Conversion Notice or Repayment Notice given by the Borrower hereunder shall be irrevocable and, subject to any options the Lenders may have hereunder in regard thereto and the Borrower’s rights hereunder in regard thereto, shall oblige the Borrower to take the action contemplated on the date specified therein.

2.14 Optional Cancellation or Reduction of the Credit Facility

          The Borrower may, at any time, upon giving at least 3 Banking Days prior written notice to the Agent, cancel in full or, from time to time, permanently reduce in part the unutilized portion of the Credit Facility; provided, however, that any such reduction shall be in a minimum amount of U.S. $10,000,000 and reductions in excess thereof shall be in integral multiples of U.S. $1,000,000. If the Credit Facility is so reduced, the Commitment of each of the Lenders thereunder shall be reduced pro rata in the same proportion that the amount of the reduction in the Credit Facility bears to the amount of the Credit Facility in effect immediately prior to such reduction.

2.15 Optional Repayment; Additional Repayment Terms

     (1) The Borrower may at any time and from time to time repay, without penalty, to the Agent for the account of the Lenders the whole or any part of any Loan owing by it together with accrued interest thereon to the date of such repayment provided that:

(a)

the Borrower shall give a Repayment Notice (executed in accordance with the definition of Officer’s Certificate) to the Agent not later than:

	(i)		11:00 a.m. (Toronto time) three Banking Days prior to the date of the proposed repayment, for Libor Loans;
	(ii)		11:00 a.m. (Toronto time) two Banking Days prior to the date of the proposed repayment, for Bankers’ Acceptances; and
	(iii)		11:00 a.m. (Toronto time) one Banking Day prior to the date of the proposed repayment, for Canadian Prime Rate Loans and U.S. Base Rate Loans;

	(b)		repayments pursuant to this Section 2.15 may only be made on a Banking Day;
	(c)		subject to the following provisions of this Section 2.15, each such repayment may only be made on the last day of the applicable Interest Period with regard to a Libor Loan that is being repaid;
	(d)		a Bankers’ Acceptance may only be repaid on its maturity unless collateralized in accordance with Section 2.15(3);
	(e)		each such repayment shall be in a minimum amount of the lesser of: (i) the minimum amount required pursuant to Section 2.5 for Drawdowns of the type of Loan proposed to be repaid and (ii) the Outstanding Principal of all Loans outstanding under the Credit Facility immediately prior to such repayment; any repayment in excess of such amount shall be in integral multiples of the amounts required pursuant to Section 2.5 for multiples in excess of the minimum amounts of Drawdowns; and
	(f)		the Borrower may not repay a portion only of an outstanding Loan unless the unpaid portion is equal to or exceeds, in the relevant currency, the minimum amount required pursuant to Section 2.5 for Drawdowns of the type of Loan proposed to be repaid.

     (2) If any Libor Loan is repaid on other than the last day of the applicable Interest Period, the Borrower shall, within three Banking Days after notice is given by the Agent, pay to the Agent for the account of the Lenders all costs, losses, premiums and expenses incurred by the Lenders by reason of the liquidation or re-deployment of deposits or other funds or for any other reason whatsoever resulting from the repayment of such Loan or any part thereof on other than the last day of the applicable Interest Period. Any Lender, upon becoming entitled to be paid such costs, losses, premiums and expenses, shall deliver to the Borrower and the Agent a certificate of the Lender certifying as to such amounts and, in the absence of manifest error, such certificate shall be conclusive and binding for all purposes.

     (3) With respect to any repayment of unmatured Bankers’ Acceptances pursuant to Section 2.15 (1)(d) or otherwise hereunder, the Borrower shall provide for the funding in full of the unmatured Bankers’ Acceptances to be repaid by paying to and depositing with the Agent cash collateral for each such unmatured Bankers’ Acceptances equal to the face amount payable at maturity thereof. The Agent shall hold such cash collateral in an interest bearing cash collateral account at rates prevailing at the time of deposit for similar accounts with the Agent; such cash collateral, such cash collateral account, any accounts receivable, claims, instruments or securities evidencing or relating to the foregoing, and any proceeds of any of the foregoing (collectively, the “Outstanding BAs Collateral”) shall be assigned to the Agent as security for the obligations of the Borrower in relation to such Bankers’ Acceptances and the Lien of the Agent created in such Outstanding BAs Collateral shall rank in priority to all other Liens and adverse claims against such Outstanding BAs Collateral. Such Outstanding BAs Collateral shall be applied to satisfy the obligations of the Borrower for such Bankers’ Acceptances as they mature and the Agent is hereby irrevocably directed by the Borrower to apply any such Outstanding BAs Collateral to such maturing Bankers’ Acceptances. The Outstanding BAs Collateral created herein shall not be released to the Borrower without the consent of the Lenders; however, interest on such deposited amounts shall be for the account

of the Borrower and may be withdrawn by the Borrower so long as no Default or Event of Default is then continuing. If, after maturity of the Bankers’ Acceptances for which such Outstanding BAs Collateral is held and application by the Agent of the Outstanding BAs Collateral to satisfy the obligations of the Borrower hereunder with respect to the Bankers’ Acceptances being repaid, any interest or other proceeds of the Outstanding BAs Collateral remains, such interest or other proceeds shall be promptly paid and transferred by the Agent to the Borrower so long as no Default or Event of Default is then continuing.

2.16 Mandatory Repayment of Credit Facility

          Subject to Section 10.2, the Borrower shall repay or pay, as the case may be, to the Agent, on behalf of the Lenders, all Loans and other Obligations outstanding under the Credit Facility on or before the Maturity Date.

2.17 Currency Excess

     (1) If the Agent shall determine that the aggregate Outstanding Principal of the outstanding Loans under the Credit Facility exceeds the maximum principal amount of the Credit Facility in United States Dollars (the amount of such excess is herein called the “Currency Excess”), then, upon written request by the Agent (which request shall detail the applicable Currency Excess), the Borrower shall repay an amount of Canadian Prime Rate Loans or U.S. Base Rate Loans under the Credit Facility within (a) if the Currency Excess exceeds 3.0% of the amount of the Credit Facility, 5 Banking Days, and (b) in all other cases, 20 Banking Days after receipt of such request, such that, except as otherwise contemplated in Section 2.17(2), the amount or the Equivalent Amount in United States Dollars of such repayments is, in the aggregate, at least equal to the Currency Excess.

     (2) If, in respect of any Currency Excess, the repayments made by the Borrower have not completely removed such Currency Excess (the remainder thereof being herein called the “Currency Excess Deficiency”), the Borrower shall within the aforementioned 5 or 20 Banking Days, as the case may be, after receipt of the aforementioned request of the Agent, place an amount equal to the Currency Excess Deficiency on deposit with the Agent in an interest-bearing account with interest at rates prevailing at the time of deposit for the account of the Borrower, to be assigned to the Agent on behalf of the Lenders by instrument satisfactory to the Agent and to be applied to maturing Bankers’ Acceptances or Libor Loans (converted if necessary at the exchange rate for determining the Equivalent Amount on the date of such application). The Agent is hereby irrevocably directed by the Borrower to apply any such sums on deposit to maturing Loans as provided in the preceding sentence. In lieu of providing funds for the Currency Excess Deficiency, as provided in the preceding provisions of this Section, the Borrower may within the said period of 5 or 20 Banking Days, as the case may be, provide to the Agent an irrevocable standby letter of credit in an amount equal to the Currency Excess Deficiency and for a term which expires not sooner than 10 Banking Days after the date of maturity of the relevant Bankers’ Acceptances or Libor Loans, as the case may be; such letter of credit shall be issued by a financial institution, and shall be on terms and conditions, acceptable to the Agent in its sole discretion. The Agent is hereby authorized and directed to draw upon such letter of credit and apply the proceeds of the same to Bankers’ Acceptances or Libor Loans as they mature. Upon the Currency Excess being eliminated as aforesaid or by virtue of subsequent changes in the exchange rate for determining the Equivalent Amount, then, provided no Default or Event of Default is then continuing, such funds on deposit, together with interest thereon, or such letters of credit shall be returned to the Borrower, in the case of funds on deposit, or shall be cancelled or reduced in amount, in the case of letters of credit.

2.18 Permitted Increase in Credit Facility

          The Borrower may, at any time and from time to time, increase the maximum principal amount of the Credit Facility by adding additional financial institutions as Lenders hereunder or by increasing the Commitments of existing Lenders with (in the latter case) the consent of such increasing Lenders, or any

combination thereof. The right to increase the maximum principal amount of the Credit Facility as aforesaid shall be subject to the following (for each such increase):

	(a)		no Default or Event of Default shall have occurred and be continuing and the Borrower shall have delivered to the Agent a certificate of an officer of the Borrower confirming the same and confirming (i) its corporate authorization to make such increase, (ii) the truth and accuracy in all material respects of its representations and warranties contained in Section 8.1 hereof as of such date, other than any such representations and warranties which expressly speak as of an earlier date and (iii) that no consents, approvals or authorizations are required for such increase (except as have been unconditionally obtained and are in full force and effect, unamended), each as at the effective date of such increase;
	(b)		the Borrower shall have delivered to the Agent an opinion of its legal counsel in form and substance as may be required by the Agent, acting reasonably (and such opinion shall, inter alia, opine as to the corporate authorization of the Borrower to effect such increase);
	(c)		after giving effect to any such increase, the maximum principal amount of the Credit Facility shall not exceed U.S. $2,000,000,000;
	(d)		the Agent shall have consented to any additional financial institution becoming a Lender, such consent not to be unreasonably withheld, conditioned or delayed; and
	(e)		the Borrower and the increasing existing Lender or the financial institution being added, as the case may be, shall execute and deliver such documentation as is required by the Agent, acting reasonably, to effect the increase in question (including the partial assignment of Loans or purchase of participations from Lenders to the extent necessary to ensure that, after giving effect to such increase, each Lender holds its Rateable Portion of each outstanding Loan under the Credit Facility) and, if applicable, to add any such new financial institution as a Lender under the Documents.

2.19 Hostile Acquisitions

     (1) In the event the Borrower wishes to utilize the proceeds of one or more Loans under the Credit Facility to, or to provide funds to any Subsidiary to, finance a Hostile Acquisition, then the following steps shall be followed:

	(a)		at least five (5) Banking Days prior to the delivery to the Agent of any Drawdown Notice pursuant to Section 2.7 requesting one or more Loans under the Credit Facility intended to be used to finance such Hostile Acquisition, the Borrower shall notify the Agent and shall provide the Agent with particulars of such Hostile Acquisition, including particulars in sufficient detail to enable each Lender to determine whether it has a conflict of interest if the proceeds of Loans from such Lender are used by the Borrower to finance such Hostile Acquisition;
	(b)		promptly after receipt of such notice and particulars from the Borrower, the Agent shall (i) notify an appropriate officer of each Lender and provide such particulars to such officer and (ii) confirm receipt (other than by way of an automated response) of such notice and particulars by each such officer;
	(c)		within three (3) Banking Days of such confirmation by the Agent of each such appropriate officer being so advised, each Lender shall notify the Agent of such Lender’s determination as to whether (i) such a conflict of interest exists or (ii) the funding of such Hostile Acquisition would contravene an internal policy of general application of such Lender (each such determination to be made by

			each such Lender in the exercise of its sole discretion, having regard to such considerations as it deems appropriate); provided that in the event such Lender does not so notify the Agent within such three (3) Banking Day period, such Lender shall be deemed to have notified the Agent that it has no such conflict of interest or contravention; and
	(d)		the Agent shall promptly notify the Borrower of each such Lender’s determination,

and, in the event that any Lender has such a conflict of interest or the funding would contravene such a policy (each, a “Conflicted Lender”), then upon such Conflicted Lender so notifying the Agent, the Conflicted Lender shall have no obligation to provide Loans to finance such Hostile Acquisition, notwithstanding any other provision of this Agreement to the contrary; provided, however, that each other Lender (each, a “Non-Conflicted Lender”) which has, or is deemed to have, no such conflict of interest or contravention shall have an obligation, up to the amount of its Commitment, to provide Loans to finance such Hostile Acquisition, and the Loans to finance such Hostile Acquisition shall be provided by each Non-Conflicted Lender in accordance with the ratio, determined prior to the provision of any Loans to finance such Hostile Acquisition, that the Commitment of such Non-Conflicted Lender under the Credit Facility bears to the aggregate Commitments of all Non-Conflicted Lenders under the Credit Facility.

     (2) If Loans are used to finance a Hostile Acquisition and there are Conflicted Lenders, subsequent Loans under the Credit Facility shall be funded firstly by Conflicted Lenders, up to the amount of their Commitments, and subsequent repayments under the Credit Facility shall be applied firstly to Non-Conflicted Lenders, in each case, until such time as the proportion that the amount of each Lender’s Outstanding Principal under the Credit Facility bears to the amount of the total Outstanding Principal of all Lenders is equal to such proportion which would have been in effect but for the application of this Section 2.19.

Such interest shall accrue daily and shall be payable in arrears on each Interest Payment Date for such Loan for the period from and including the Drawdown Date or the preceding Conversion Date or Interest Payment Date, as the case may be, for such Loan to and including the day preceding such Interest Payment Date and shall be calculated on the principal amount of the Canadian Prime Rate Loan outstanding during such period and on the basis of the actual number of

days elapsed in a year of 365 days. Changes in the Canadian Prime Rate shall cause an immediate adjustment of the interest rate applicable to such Loans without the necessity of any notice to the Borrower.

5.2 Interest on U.S. Base Rate Loans

5.3 Interest on Libor Loans

          The Borrower shall pay interest on each Libor Loan owing by it during each Interest Period applicable thereto in United States Dollars at a rate per annum, calculated on the basis of a 360 day year, equal to the Libor Rate with respect to such Interest Period plus the Applicable Pricing Rate.

5.4 Interest Act (Canada)

     (1) Whenever a rate of interest hereunder is calculated on the basis of a year (the “deemed year”) which contains fewer days than the actual number of days in the calendar year of calculation, such rate of interest shall be expressed as a yearly rate for purposes of the Interest Act (Canada) by multiplying such rate of interest by the actual number of days in the calendar year of calculation and dividing it by the number of days in the deemed year.

     (2) Whenever a rate of interest or other rate per annum hereunder is expressed or calculated on the basis of a year of 360 days, such rate of interest or other rate shall be expressed as a rate per annum, calculated on the basis of a 365-day year, by multiplying such rate of interest or other rate by 365 and dividing it by 360.

The rates of interest specified in this Agreement are intended to be nominal rates and not effective rates. Interest calculated hereunder shall be calculated using the nominal rate method and not the effective rate method of calculation.

5.6 Standby Fees

     (1) The Borrower shall pay to the Agent for the account of the Lenders a standby fee in United States Dollars in respect of the Credit Facility calculated at a rate per annum equal to the Applicable Pricing Rate on the

Fees determined in accordance with this Section shall accrue daily from and after the date hereof and be payable by the Borrower (a) quarterly in arrears, (b) on cancellation in full of the Credit Facility, and (c) on the Maturity Date.

5.9 Waiver

          To the extent permitted by applicable law, the covenant of the Borrower to pay interest at the rates provided herein shall not merge in any judgment relating to any obligation of the Borrower to the Lenders or the Agent and any provision of the Interest Act (Canada) or Judgment Interest Act (Alberta) which restricts any rate of interest set forth herein shall be inapplicable to this Agreement and is hereby waived by the Borrower.

5.10 Maximum Rate Permitted by Law

          No interest or fee to be paid hereunder shall be paid at a rate exceeding the maximum rate permitted by applicable law.

	(c)		each draft drawn by the Borrower and presented for acceptance by a Lender shall be drawn on the standard form of such Lender in effect at the time; provided, however, that the Agent may require the Lenders to use a generic form of Bankers’ Acceptance, in a form satisfactory to each Lender, acting reasonably, provided by the Agent for such purpose in place of the Lenders’ own forms;
	(d)		subject to Section 6.3(e) below, Bankers’ Acceptances shall be signed by duly authorized officers of the Borrower or, in the alternative, the signatures of such officers may be mechanically reproduced in facsimile thereon and Bankers’ Acceptances bearing such facsimile signatures shall be binding on the Borrower as if they had been manually executed and delivered by such officers on behalf of the Borrower; notwithstanding that any person whose manual or facsimile signature appears on any Bankers’ Acceptance may no longer be an authorized signatory for the Borrower on the date of issuance of a Bankers’ Acceptance, such signature shall nevertheless be valid and sufficient for all purposes as if such authority had remained in force at the time of such issuance and any such Bankers’ Acceptance shall be binding on the Borrower; and
	(e)		in lieu of signing Bankers’ Acceptances in accordance with Section 6.3(d) above, the Borrower may provide a Power of Attorney to a Lender; for so long as a Power of Attorney is in force with respect to a given Lender, such Lender shall execute and deliver Bankers’ Acceptances on behalf of the Borrower in accordance with the provisions thereof and, for certainty, all references herein to drafts drawn by the Borrower, Bankers’ Acceptances executed by the Borrower or similar expressions shall be deemed to include Bankers’ Acceptances executed in accordance with a Power of Attorney, unless the context otherwise requires.

6.4 Power of Attorney; Provision of Bankers’ Acceptances to Lenders

     (1) Unless revoked with respect to a given Lender in accordance herewith, the Borrower hereby appoints each Lender, acting by any authorized signatory of the Lender in question, the attorney of the Borrower:

	(a)		to sign for and on behalf and in the name of the Borrower as drawer, drafts in such Lender’s standard form which are depository bills as defined in the Depository Bills and Notes Act (Canada) (the “DBNA”), payable to a “clearing house” (as defined in the DBNA) including CDS Clearing and Depository Services Inc., or its nominee, CDS & Co. (the “clearing house”);
	(b)		for drafts which are not depository bills, to sign for and on behalf and in the name of the Borrower as drawer and to endorse on its behalf, Bankers’ Acceptances drawn on the Lender payable to the order of the undersigned or payable to the order of such Lender;
	(c)		to fill in the amount, date and maturity date of such Bankers’ Acceptances; and
	(d)		to deposit and/or deliver such Bankers’ Acceptances which have been accepted by such Lender,

provided that such acts in each case are to be undertaken by the Lender in question strictly in accordance with instructions given to such Lender by the Borrower as provided in this Section 6.4. For certainty, signatures of any authorized signatory of a Lender may be mechanically reproduced in facsimile on Bankers’ Acceptances in accordance herewith and such facsimile signatures shall be binding and effective as if they had been manually executed by such authorized signatory of such Lender.

          Instructions from the Borrower to a Lender relating to the execution, completion, endorsement, deposit and/or delivery by that Lender on behalf of the Borrower of Bankers’ Acceptances which the Borrower wishes to submit to the Lender for acceptance by the Lender shall be communicated by the Borrower in writing to the Agent by delivery to the Agent of Drawdown Notices, Conversion Notices and Rollover Notices, as the case may be, in accordance with this Agreement which, in turn, shall be communicated by the Agent, on behalf of the Borrower, to the Lender.

          The communication in writing by the Borrower, or on behalf of the Borrower by the Agent, to the Lender of the instructions set out in the Drawdown Notices, Conversion Notices and Rollover Notices referred to above shall constitute (a) the authorization and instruction of the Borrower to the Lender to sign for and on behalf and in the name of the Borrower as drawer the requested Bankers’ Acceptances and to complete and/or endorse Bankers’ Acceptances in accordance with such information as set out above and (b) the request of the Borrower to the Lender to accept such Bankers’ Acceptances and deposit the same with the clearing house or deliver the same, as the case may be, in each case in accordance with this Agreement and such instructions. The Borrower acknowledges that a Lender shall not be obligated to accept any such Bankers’ Acceptances except in accordance with the provisions of this Agreement.

          A Lender shall be and it is hereby authorized to act on behalf of the Borrower upon and in compliance with instructions communicated to that Lender as provided herein if the Lender reasonably believes such instructions to be genuine. If a Lender accepts Bankers’ Acceptances pursuant to any such instructions, that Lender shall confirm particulars of such instructions and advise the Agent that it has complied therewith by notice in writing addressed to the Agent and served personally or sent by facsimile transmission or other electronic transmission in accordance with the provisions hereof. A Lender’s actions in compliance with such instructions, confirmed and advised to the Agent by such notice, shall be conclusively deemed to have been in accordance with the instructions of the Borrower.

          This Power of Attorney may be revoked by the Borrower with respect to any particular Lender at any time upon not less than 5 Banking Days’ prior written notice served upon the Lender in question and the Agent, provided that no such revocation shall reduce, limit or otherwise affect the obligations of the Borrower in respect of any Bankers’ Acceptance executed, completed, endorsed, deposited and/or delivered in accordance herewith prior to the time at which such revocation becomes effective.

     (2) Unless the Borrower has provided Powers of Attorney to the Lenders, to facilitate Drawdowns, Rollovers or Conversions of Bankers’ Acceptances, the Borrower shall, upon execution of this Agreement and thereafter from time to time as required by all Lenders, provide to the Agent for delivery to each Lender drafts drawn in blank by the Borrower (pre-endorsed and otherwise in fully negotiable form, if applicable) in quantities sufficient for each Lender to fulfil its obligations hereunder. Any such pre-signed drafts which are delivered by the Borrower to the Agent or a Lender shall be held in safekeeping by the Agent or such Lender, as the case may be, with the same degree of care as if they were the Agent’s or such Lender’s property, and shall only be dealt with by the Lenders and the Agent in accordance herewith. No Lender shall be responsible or liable for its failure to make its share of any Drawdown, Rollover or Conversion of Bankers’ Acceptances required hereunder if the cause of such failure is, in whole or in part, due to the failure of the Borrower to provide such pre-signed drafts to the Agent (for delivery to such Lender) on a timely basis.

     (3) By 12:00 noon (Toronto time) on the applicable Drawdown Date, Conversion Date or Rollover Date, the Borrower shall (a) either deliver to each Lender in Toronto, or, if previously delivered, be deemed to have authorized each Lender to complete and accept, or (b) where the Borrower has previously executed and delivered a Power of Attorney to the Lender, be deemed to have authorized each such Lender to sign on behalf of the Borrower, complete and accept, drafts drawn by the Borrower on such Lender in a principal amount at maturity equal to such Lender’s share of the Bankers’ Acceptances specified by the Borrower in the relevant Drawdown Notice, Conversion Notice or Rollover Notice, as the case may be, as notified to the Lenders by the Agent.

6.5 Mechanics of Issuance

     (1) Upon receipt by the Agent of a Drawdown Notice, Conversion Notice or Rollover Notice from the Borrower requesting the issuance of Bankers’ Acceptances, the Agent shall promptly notify the Lenders thereof and advise each Lender of the aggregate face amount of Bankers’ Acceptances to be accepted by such Lenders, the date of issue and the Interest Period for such Loan; the apportionment among the Lenders of the face amounts of Bankers’ Acceptances to be accepted by each Lender shall be determined by the Agent by reference and in proportion to the respective Commitment of each Lender, provided that, when such apportionment cannot be evenly made, the Agent shall round allocations amongst such Lenders consistent with the Agent’s normal money market practices.

     (2) On each Drawdown Date, Rollover Date or Conversion Date involving the issuance of Bankers’ Acceptances:

	(a)		before 11:00 a.m. (Toronto time) on such date, the Agent shall determine the CDOR Rate in respect of an issue of bankers’ acceptances in a comparable amount and with comparable maturity to the Bankers’ Acceptances proposed to be issued on such date;
	(b)		on or about 11:00 a.m. (Toronto time) on such date, the Agent shall advise each Lender of the applicable BA Discount Rate;
	(c)		each Lender shall complete and accept, in accordance with the Drawdown Notice, Conversion Notice or Rollover Notice delivered by the Borrower and advised by the Agent in connection with such issue, its share of the Bankers’ Acceptances to be issued on such date and shall purchase such Bankers’ Acceptances for its own account at a purchase price which reflects the BA Discount Rate applicable to such issue; and
	(d)		in the case of a Drawdown, each Lender shall, for same day value on the Drawdown Date, remit the Discount Proceeds or advance the BA Equivalent Advance, as the case may be, payable by such Lender (net of the acceptance fee payable to such Lender pursuant to Section 6.2) to the

Agent for the account of the Borrower; the Agent shall make such funds available to the Borrower for same day value on such date.

     (3) Each Lender may at any time and from time to time hold, sell, rediscount or otherwise dispose of any or all Bankers’ Acceptances accepted and purchased by it for its own account.

6.6 Rollover, Conversion or Payment on Maturity

          In anticipation of the maturity of Bankers’ Acceptances, the Borrower shall, subject to and in accordance with the requirements hereof, do one or a combination of the following with respect to the aggregate face amount at maturity of all such maturing Bankers’ Acceptances:

	(a)		(i) deliver to the Agent a Rollover Notice that the Borrower intends to draw and present for acceptance on the maturity date new Bankers’ Acceptances in an aggregate face amount up to the aggregate amount of the maturing Bankers’ Acceptances and (ii) on the maturity date pay to the Agent for the account of the Lenders an additional amount equal to the difference between the aggregate face amount of the maturing Bankers’ Acceptances and the Discount Proceeds of such new Bankers’ Acceptances;
	(b)		(i) deliver to the Agent a Conversion Notice requesting a Conversion of the maturing Bankers’ Acceptances to another type of Loan under the Credit Facility and (ii) on the maturity date pay to the Agent for the account of the Lenders an amount equal to the difference, if any, between the aggregate face amount of the maturing Bankers’ Acceptances and the amount of the Loans into which Conversion is requested; or
	(c)		on the maturity date of the maturing Bankers’ Acceptances, pay to the Agent for the account of the Lenders an amount equal to the aggregate face amount of such Bankers’ Acceptances.

If the Borrower fails to so notify the Agent or make such payments on maturity, the Agent shall effect a Conversion into a Canadian Prime Rate Loan of the entire amount of such maturing Bankers’ Acceptances as if a Conversion Notice had been given by the Borrower to the Agent to that effect.

6.7 Restriction on Rollovers and Conversions

          Subject to the other provisions hereof, Conversions and Rollovers of Bankers’ Acceptances may only occur on the maturity date thereof.

6.8 Rollovers

          In order to satisfy the continuing liability of the Borrower to a Lender for the face amounts of maturing Bankers’ Acceptances accepted by such Lender, the Lender shall receive and retain for its own account the Discount Proceeds of new Bankers’ Acceptances issued on a Rollover, and the Borrower shall on the maturity date of the Bankers’ Acceptances being rolled over pay to the Agent for the account of the Lenders an amount equal to the difference between the face amounts of the maturing Bankers’ Acceptances and the Discount Proceeds from the new Bankers’ Acceptances together with the acceptance fees to which the Lenders are entitled pursuant to Section 6.2.

6.9 Conversion into Bankers’ Acceptances

          In respect of Conversions into Bankers’ Acceptances, in order to satisfy the continuing liability of the Borrower to the Lenders for the amount of the converted Loan, each Lender shall receive and retain for its own account the Discount Proceeds of the Bankers’ Acceptances issued upon such Conversion, and the Borrower shall

on the Conversion Date pay to the Agent for the account of the Lenders an amount equal to the difference between the principal amount of the converted Loan and the aggregate Discount Proceeds from the Bankers’ Acceptances issued on such Conversion, together with the acceptance fees to which the Lenders are entitled pursuant to Section 6.2.

6.10 Conversion from Bankers’ Acceptances

          In order to satisfy the continuing liability of the Borrower to the Lenders for an amount equal to the aggregate face amount of the maturing Bankers’ Acceptances converted to another type of Loan, the Agent shall record the obligations of the Borrower to the Lenders in respect of those maturing Bankers’ Acceptances as Loans of the type into which such continuing liability has been converted.

6.11 BA Equivalent Advances

          Notwithstanding the foregoing provisions of this Article, a Non-Acceptance Lender shall, in lieu of accepting Bankers’ Acceptances, make a BA Equivalent Advance. The amount of each BA Equivalent Advance shall be equal to the Discount Proceeds which would be realized from a hypothetical sale of those Bankers’ Acceptances which, but for this Section, such Lender would otherwise be required to accept as part of such a Drawdown of, Conversion into or Rollover of Bankers’ Acceptances. To determine the amount of such Discount Proceeds, the hypothetical sale shall be deemed to take place at the applicable BA Discount Rate for such Loan. Any BA Equivalent Advance shall be made on the relevant Drawdown Date, Rollover Date or Conversion Date as the case may be and shall remain outstanding for the term of the relevant Bankers’ Acceptances. Concurrent with the making of a BA Equivalent Advance, a Non-Acceptance Lender shall be entitled to deduct therefrom an amount equal to the acceptance fee which, but for this Section, such Lender would otherwise be entitled to receive as part of such Loan. Subject to Section 6.6, upon the maturity date for such Bankers’ Acceptances, the Borrower shall pay to each Non-Acceptance Lender an amount equal to the face amount at maturity of the Bankers’ Acceptances which, but for this Section, such Lender would otherwise be required to accept as part of such a Drawdown of, Conversion into or Rollover of Bankers’ Acceptances as repayment of the amount of its BA Equivalent Advance plus payment of the interest accrued and payable thereon to such maturity date.

          All references herein to “Loans” and “Bankers’ Acceptances” shall, unless otherwise expressly provided herein or unless the context otherwise requires, be deemed to include BA Equivalent Advances made by a Non-Acceptance Lender as part of a Drawdown of, Conversion into or Rollover of Bankers’ Acceptances.

6.12 Termination of Bankers’ Acceptances

          If at any time a Lender ceases to accept bankers’ acceptances in the ordinary course of its business, such Lender shall be deemed to be a Non-Acceptance Lender and shall make BA Equivalent Advances in lieu of accepting Bankers’ Acceptances under this Agreement.

	(b)		without the necessity of notice to the Borrower.
	(2)		For any Loans outstanding as of the effective date of a change in an Applicable Pricing Rate:

	(a)		Encumbrances.

inclusive, of this Section 9.2(b) above) so long as the Borrower or such Material Subsidiary is the surviving entity of such merger or amalgamation; provided that:

	(A)		in each case, no Default and no Event of Default shall have occurred and be continuing, or will occur as a result of such transaction, or shall exist immediately after the consummation of such transaction; and
	(B)		in each case, where the transaction involves the Borrower, the Borrower, surviving entity or other successor thereto (each, a “Successor”) shall have executed and delivered or caused to be executed and delivered to the Agent such instruments and shall have done or caused to be done such things as, in the reasonable opinion of Lenders’ Counsel, are necessary or advisable to establish that upon the consummation of such transaction: (I) the Successor will have assumed all the covenants and obligations of the Borrower under this Agreement and the other Documents and (II) this Agreement and the other Documents, as the case may be, will be valid and binding obligations of the Successor, entitling the Lenders and the Agent, as against the Successor, to exercise all their respective rights under this Agreement and the other Documents to the same extent that the Lenders and the Agent were entitled to exercise such rights against the Borrower prior to such transaction.

Notwithstanding the foregoing but for greater certainty, the disposition of assets as a result of the securitization of assets shall only be included in the foregoing calculation if the assets are transferred to create a securitized asset pool or to increase the overall size of a securitized asset pool but not if the assets are transferred to replenish a depleting securitized asset pool.

			Debt of Subsidiaries shall not at any time exceed U.S. $650,000,000 in the aggregate.

9.3 Agent May Perform Covenants

          If the Borrower fails to perform any covenants on its part herein contained, subject to any consents or notice or cure periods required by Section 10.1, the Agent may give notice to the Borrower of such failure and if such covenant remains unperformed, the Agent may, in its discretion but need not, perform any such covenant capable of being performed by the Agent and if the covenant requires the payment or expenditure of money, the Agent may, upon having received approval of all Lenders, make such payments or expenditure and all sums so expended shall be forthwith payable by the Borrower to the Agent on behalf of the Lenders and shall bear interest at the applicable interest rate provided in Section 5.8 for amounts due in Canadian Dollars or United States Dollars,

as the case may be. No such performance, payment or expenditure by the Agent shall be deemed to relieve the Borrower of any default hereunder or under the other Documents.

10.4 Remedies Cumulative and Waivers

          For greater certainty, it is expressly understood and agreed that the rights and remedies of the Lenders and the Agent hereunder or under any other Document are cumulative and are in addition to and not in substitution for any rights or remedies provided by law or by equity; and any single or partial exercise by the Lenders or by the Agent of any right or remedy for a default or breach of any term, covenant, condition or agreement contained in this Agreement or other Document shall not be deemed to be a waiver of or to alter, affect or prejudice any other right or remedy or other rights or remedies to which any one or more of the Lenders and the Agent may be lawfully entitled for such default or breach.

ARTICLE 11
CHANGE OF CIRCUMSTANCES

11.1 Market Disruption Respecting Libor Loans

          In the event that at any time subsequent to the giving of a Drawdown Notice, Rollover Notice or Conversion Notice to the Agent by the Borrower with regard to any requested Libor Loan, but before the date of the Drawdown, Rollover or Conversion, as the case may be, the Agent (acting reasonably) makes a determination, which shall be conclusive and binding upon the Borrower, that:

	(a)		by reason of circumstances affecting the London interbank market, adequate and fair means do not exist for ascertaining the rate of interest with respect to, or deposits are not available in sufficient amounts in the ordinary course of business at the rate determined hereunder to fund, a requested Libor Loan during the ensuing Interest Period selected;
	(b)		the making or continuing of the requested Libor Loan by the Lenders has been made impracticable by the occurrence of an event which materially adversely affects the London interbank market generally; or
	(c)		the Libor Rate shall no longer represent the effective cost to any Lender of United States Dollar deposits in such market for the relevant Interest Period,

then the Agent shall give notice thereof to the Borrower as soon as possible after such determination and the Borrower shall, within one Banking Day after receipt of such notice and in replacement of the Drawdown Notice, Rollover Notice or Conversion Notice, as the case may be, previously given by the Borrower, give the Agent a Drawdown Notice or a Conversion Notice, as the case may be, which specifies the Drawdown of any other Loan or the Conversion of the relevant Libor Loan on the last day of the applicable Interest Period into any other Loan which would not be affected by the notice from the Agent pursuant to this Section 11.1. In the event the Borrower fails to give, if applicable, a valid replacement Conversion Notice with respect to the maturing Libor Loans which were the subject of a Rollover Notice, such maturing Libor Loans shall be converted on the last day of the applicable Interest Period into U.S. Base Rate Loans as if a Conversion Notice had been given to the Agent by the Borrower pursuant to the provisions hereof. In the event the Borrower fails to give, if applicable, a valid replacement Drawdown Notice with respect to a Drawdown originally requested by way of a Libor Loan, then the Borrower shall be deemed to have requested a Drawdown by way of a U.S. Base Rate Loan in the amount specified in the original Drawdown Notice and, on the originally requested Drawdown Date, the Lenders (subject to the other provisions hereof) shall make available the requested amount by way of a U.S. Base Rate Loan.

11.2 Market Disruption Respecting Bankers’ Acceptances

          If the Agent (acting reasonably) makes a determination, which determination shall be conclusive and binding upon the Borrower, and notifies the Borrower, that:

	(a)		there no longer exists an active market for bankers’ acceptances accepted by the Lenders; or
	(b)		the BA Discount Rate does not accurately reflect the discount rate which would be applicable to a sale of Bankers’ Acceptances in the market;

then:

	(c)		the right of the Borrower to request Bankers’ Acceptances or BA Equivalent Advances from any Lender shall be suspended until the Agent determines that the circumstances causing such suspension no longer exist, and so notifies the Borrower;
	(d)		any outstanding Drawdown Notice requesting Loans by way of Bankers’ Acceptances or BA Equivalent Advances shall be deemed to be a Drawdown Notice requesting Loans by way of Canadian Prime Rate Loans in the amount specified in the original Drawdown Notice;
	(e)		any outstanding Conversion Notice requesting a Conversion of a Loan by way of U.S. Base Rate Loans or Libor Loans into a Loan by way of Bankers’ Acceptances or BA Equivalent Advances shall be deemed to be a Conversion Notice requesting a Conversion of such Loan into a Loan by way of Canadian Prime Rate Loan; and
	(f)		any outstanding Rollover Notice requesting a Rollover of a Loan by way of Bankers’ Acceptances or BA Equivalent Advances shall be deemed to be a Conversion Notice requesting a Conversion of such Loan into a Loan by way of Canadian Prime Rate Loan.

The Agent shall promptly notify the Borrower and the Lenders of any suspension of the Borrower’s right to request the Bankers’ Acceptances or BA Equivalent Advances and of any termination of any such suspension.

11.3 Change in Law

     (1) If the adoption of any applicable law, regulation, treaty or official directive (whether or not having the force of law) or any change therein or in the interpretation or application thereof by any court or by any Governmental Authority or any other entity charged with the interpretation or administration thereof or compliance by a Lender with any request or direction (whether or not having the force of law) of any such court, Governmental Authority or other entity in each case after the date hereof:

	(a)		subjects such Lender to, or causes the withdrawal or termination of a previously granted exemption with respect to, any Taxes (other than Taxes on such Lender’s overall income or capital), or changes the basis of taxation of payments due to such Lender, or increases any existing Taxes (other than Taxes on such Lender’s overall income or capital) on payments of principal, interest or other amounts payable by the Borrower to such Lender under this Agreement;
	(b)		imposes, modifies or deems applicable any reserve, liquidity, special deposit, regulatory or similar requirement against assets or liabilities held by, or deposits in or for the account of, or loans by such Lender, or any acquisition of funds for loans or commitments to fund loans or obligations in respect of undrawn, committed lines of credit or in respect of Bankers’ Acceptances accepted by such Lender;

	(c)		imposes on such Lender or requires there to be maintained by such Lender any capital adequacy or additional capital requirements (including, without limitation, a requirement which affects such Lender’s allocation of capital resources to its obligations) in respect of any Loan or obligation of such Lender hereunder, or any other condition with respect to this Agreement; or
	(d)		directly or indirectly affects the cost to such Lender of making available, funding or maintaining any Loan (other than changes in Taxes on such Lender’s overall income) or otherwise imposes on such Lender any other condition or requirement affecting this Agreement or any Loan or any obligation of such Lender hereunder;

and the result of (a), (b), (c) or (d) above, in the sole determination of such Lender acting in good faith, is:

	(e)		to increase the cost to such Lender of performing its obligations hereunder with respect to any Loan;
	(f)		to reduce any amount received or receivable by such Lender hereunder or its effective return hereunder or on its capital in respect of any Loan or the Credit Facility;
	(g)		to reduce the standby fees payable to such Lender pursuant to Section 5.6; or
	(h)		to cause such Lender to make any payment with respect to or to forego any return on or calculated by reference to, any amount received or receivable by such Lender hereunder with respect to any Loan or the Credit Facility;

such Lender shall determine that amount of money which shall compensate the Lender for such increase in cost, payments to be made or reduction in income or return or interest foregone (herein referred to as “Additional Compensation”). Upon a Lender having determined that it is entitled to Additional Compensation in accordance with the provisions of this Section, such Lender shall promptly so notify the Borrower and the Agent. The relevant Lender shall provide the Borrower and the Agent with a photocopy of the relevant law, rule, guideline, regulation, treaty or official directive (or, if it is impracticable to provide a photocopy, a written summary of the same) and a certificate of a duly authorized officer of such Lender setting forth the Additional Compensation and the basis of calculation therefor, which shall be conclusive evidence of such Additional Compensation in the absence of manifest error. The Borrower shall pay to such Lender within 10 Banking Days of the giving of such notice such Lender’s Additional Compensation. Each of the Lenders shall be entitled to be paid such Additional Compensation from time to time to the extent that the provisions of this Section are then applicable notwithstanding that any Lender has previously been paid any Additional Compensation.

     (2) Each Lender agrees that it will not claim Additional Compensation from the Borrower under Section 11.3(1):

	(a)		if it is not generally claiming similar compensation from its other customers in similar circumstances; or
	(b)		in respect of any period greater than 9 months prior to the delivery of notice in respect thereof by such Lender, unless the adoption, change or other event or circumstance giving rise to the claim for Additional Compensation is retroactive or is retroactive in effect.

11.4 Prepayment of Portion

          In addition to the other rights and options of the Borrower hereunder and notwithstanding any contrary provisions hereof, if a Lender gives the notice provided for in Section 11.3 with respect to any Loan (an “Affected Loan”), the Borrower may, upon 2 Banking Days notice to that effect given to such Lender and the

Agent (which notice shall be irrevocable), prepay in full without penalty such Lender’s Rateable Portion of the Affected Loan outstanding together with accrued and unpaid interest on the principal amount so prepaid up to the date of such prepayment, such Additional Compensation as may be applicable to the date of such payment and all costs, losses and expenses incurred by such Lender by reason of the liquidation or re-deployment of deposits or other funds or for any other reason whatsoever resulting from the repayment of such Affected Loan or any part thereof on other than the last day of the applicable Interest Period, and upon such payment being made that Lender’s obligations to make such Affected Loans to the Borrower under this Agreement shall terminate.

11.5 Illegality

          If a Lender determines, in good faith, that the adoption of any applicable law, regulation, treaty or official directive (whether or not having the force of law) or any change therein or in the interpretation or application thereof by any court or by any Governmental Authority or any other entity charged with the interpretation or administration thereof or compliance by a Lender with any request or direction (whether or not having the force of law) of any such court, Governmental Authority or other entity, now or hereafter makes it unlawful or impossible for any Lender to make, fund or maintain a Loan under the Credit Facility or to give effect to its obligations in respect of such a Loan, such Lender may, by written notice thereof to the Borrower and to the Agent declare its obligations under this Agreement in respect of such Loan to be terminated whereupon the same shall forthwith terminate, and the Borrower shall, within the time required by such law (or at the end of such longer period as such Lender at its discretion has agreed), either effect a Conversion of such Loan in accordance with the provisions hereof (if such Conversion would resolve the unlawfulness or impossibility) or prepay the principal of such Loan together with accrued interest, such Additional Compensation as may be applicable with respect to such Loan to the date of such payment and all costs, losses and expenses incurred by the Lender by reason of the liquidation or re-deployment of deposits or other funds or for any other reason whatsoever resulting from the repayment of such Loan or any part thereof on other than the last day of the applicable Interest Period. If any such change shall only affect a portion of such Lender’s obligations under this Agreement which is, in the opinion of such Lender and the Agent, severable from the remainder of this Agreement so that the remainder of this Agreement may be continued in full force and effect without otherwise affecting any of the obligations of the Agent, the other Lenders or the Borrower hereunder, such Lender shall only declare its obligations under that portion so terminated.

ARTICLE 12
COSTS, EXPENSES AND INDEMNIFICATION

12.1 Costs and Expenses

          The Borrower shall pay promptly upon notice from the Agent all reasonable out-of-pocket costs and expenses of the Lenders and the Agent in connection with the Documents and the establishment of the Credit Facility, including, without limitation, in connection with preparation, printing, execution and delivery of this Agreement and the other Documents whether or not any Drawdown has been made hereunder, and also including the reasonable fees and out-of-pocket costs and expenses of Lenders’ Counsel with respect thereto and with respect to advising the Agent and the Lenders as to their rights and responsibilities under this Agreement and the other Documents.

Section 12.3) is a party or subject thereto), together with interest thereon from and after such 15^th day if such payment is not made by such time.

12.2 General Indemnity

          In addition to any liability of the Borrower to any Lender or the Agent under any other provision hereof, the Borrower shall indemnify each Indemnified Party and hold each Indemnified Party harmless against any losses, claims, costs, damages or liabilities (including, without limitation, any loss of profits or fees anticipated hereunder, any expense or cost incurred in the liquidation and re-deployment of funds acquired to fund or maintain any portion of a Loan and reasonable out-of-pocket expenses and reasonable legal fees on a solicitor and his own client basis) incurred by the same as a result of or in connection with the Credit Facility or the Documents, including as a result of or in connection with:

	(a)		any cost or expense incurred by reason of the liquidation or re-deployment in whole or in part of deposits or other funds required by any Lender to fund or maintain any Loan as a result of the Borrower’s failure to complete a Drawdown or to make any payment, repayment or prepayment on the date required hereunder or specified by it in any notice given hereunder;

The provisions of this Section shall survive repayment of the Obligations.

12.3 Judgment Currency

     (1) If for the purpose of obtaining or enforcing judgment against the Borrower in any court in any jurisdiction, it becomes necessary to convert into any other currency (such other currency being hereinafter in this Section referred to as the “Judgment Currency”) an amount due in Canadian Dollars or United States Dollars under this Agreement, the conversion shall be made at the rate of exchange prevailing on the Banking Day immediately preceding:

	(a)		the date of actual payment of the amount due, in the case of any proceeding in the courts of any jurisdiction that will give effect to such conversion being made on such date; or
	(b)		the date on which the judgment is given, in the case of any proceeding in the courts of any other jurisdiction (the date as of which such conversion is made pursuant to this Section being hereinafter in this Section referred to as the “Judgment Conversion Date”).

     (2) If, in the case of any proceeding in the court of any jurisdiction referred to in Section 12.3(1)(b), there is a change in the rate of exchange prevailing between the Judgment Conversion Date and the date of actual payment of the amount due, the Borrower shall pay such additional amount (if any) as may be necessary to ensure that the amount paid in the Judgment Currency, when converted at the rate of exchange prevailing on the date of payment, will produce the amount of Canadian Dollars or United States Dollars, as the case may be, which could have been purchased with the amount of Judgment Currency stipulated in the judgment or judicial order at the rate of exchange prevailing on the Judgment Conversion Date.

     (3) Any amount due from the Borrower under the provisions of Section 12.3(2) shall be due as a separate debt and shall not be affected by judgment being obtained for any other amounts due under or in respect of this Agreement.

     (4) The term “rate of exchange” in this Section 12.3 means the noon rate of exchange for Canadian interbank transactions in Canadian Dollars or United States Dollars, as the case may be, in the Judgment Currency published by the Bank of Canada for the day in question, or if such rate is not so published by the Bank of Canada, such term shall mean the Equivalent Amount of the Judgment Currency.

12.4 Limits on Liability of Indemnified Parties

          No Indemnified Party shall have any liability to the Borrower, any Subsidiary or any person asserting claims on behalf of, or in right of, the Borrower or any Subsidiary thereof in connection with or as a result of the Credit Facility, this Agreement or any other Documents or any transaction contemplated hereby or thereby, except to the extent (and only to the extent) that any losses, claims, damages, liabilities or expenses incurred by the Borrower, such Subsidiary or other person are determined by a final non-appealable judgment of a court of competent jurisdiction to have (a) resulted solely by reason of the gross negligence or wilful misconduct of such Indemnified Party or (b) in respect only of a Lender, resulted from the intentional failure of such Lender to advance funds under its Commitment when all conditions precedent to a Drawdown have been satisfied. In any event, and notwithstanding the foregoing or any other provision hereof or of the other Documents to the contrary, no Indemnified Party shall be liable for any special, indirect, consequential or punitive damages in connection with or as a result of the Credit Facility, this Agreement or any other Document or any transaction contemplated hereby or thereby.

ARTICLE 13
THE AGENT AND ADMINISTRATION OF THE CREDIT FACILITY

13.1 Authorization and Action

     (1) Each Lender hereby irrevocably appoints and authorizes the Agent to be its agent in its name and on its behalf to exercise such rights or powers granted to the Agent or the Lenders under this Agreement to the extent specifically provided herein and on the terms hereof, together with such powers as are reasonably incidental thereto and the Agent hereby accepts such appointment and authorization. As to any matters not expressly provided for by this Agreement, the Agent shall not be required to exercise any discretion or take any action, but, subject to Section 14.10, shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority of the Lenders and such instructions shall be binding upon all Lenders; provided, however, that the Agent shall not be required to take any action which exposes the Agent to liability in such capacity or which could result in the Agent’s incurring any costs and expenses, without provision being made for indemnity of the Agent by the Lenders against any loss, liability, cost or expense incurred, or to be incurred or which is contrary to this Agreement or applicable law.

     (2) The Lenders agree that all decisions as to actions to be or not to be taken, as to consents or waivers to be given or not to be given, as to determinations to be made and otherwise in connection with this Agreement and the Documents, shall be made upon the decision of the Majority of the Lenders except in respect of a decision or determination where it is specifically provided in this Agreement that “all of the Lenders” or “the Lenders” or words to similar effect, or the Agent alone, is to be responsible for same. Each of the Lenders shall be bound by and agrees to abide by and adopt all decisions made as aforesaid and covenants in all communications with the Borrower to act in concert and to join in the action, consent, waiver, determination or other matter decided as aforesaid.

13.2 Procedure for Making Loans

     (1) The Agent shall make Loans available to the Borrower as required hereunder by debiting the account of the Agent to which the Lenders’ Rateable Portions of such Loans have been credited in accordance with Section 2.12 (or causing such account to be debited) and, in the absence of other arrangements agreed to by the Agent and the Borrower in writing, by crediting the United States Dollar or Canadian Dollar account of the Borrower, as applicable, at the Agent or, at the expense of the Borrower, transferring (or causing to be transferred) like funds in accordance with the instructions of the Borrower as set forth in the Drawdown Notice, Rollover Notice or Conversion Notice, as the case may be, in respect of each Loan; provided that the obligation of the Agent hereunder to effect such a transfer shall be limited to taking such steps as are commercially reasonable to implement such instructions, which steps once taken shall constitute conclusive and binding evidence that such funds were advanced hereunder in accordance with the provisions relating thereto and the Agent shall not be liable for any damages, claims or costs which may be suffered by the Borrower and occasioned by the failure of such Loan to reach the designated destination.

     (2) Unless the Agent has been notified by a Lender at least one Banking Day prior to the Drawdown Date, Rollover Date or Conversion Date, as the case may be, requested by the Borrower that such Lender will not make available to the Agent its Rateable Portion of such Loan, the Agent may assume that such Lender has made or will make such portion of the Loan available to the Agent on the Drawdown Date, Rollover Date or Conversion Date, as the case may be, in accordance with the provisions hereof and the Agent may, but shall be in no way obligated to, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent such Lender shall not have so made its Rateable Portion of a Loan available to the Agent, such Lender agrees to pay to the Agent forthwith on demand such Lender’s Rateable Portion of the Loan and all reasonable costs and expenses incurred by the Agent in connection therewith together with interest thereon (at the rate payable hereunder by the Borrower in respect of such Loan or, in the case of funds made available in

anticipation of a Lender remitting proceeds of a Bankers’ Acceptance, at the rate of interest per annum applicable to Canadian Prime Rate Loans) for each day from the date such amount is made available to the Borrower until the date such amount is paid to the Agent; provided, however, that notwithstanding such obligation if such Lender fails to so pay, the Borrower covenants and agrees that, without prejudice to any rights the Borrower may have against such Lender, it shall repay such amount to the Agent forthwith after demand therefor by the Agent. The amount payable to the Agent pursuant hereto shall be set forth in a certificate delivered by the Agent to such Lender and the Borrower (which certificate shall contain reasonable details of how the amount payable is calculated) and shall be conclusive and binding evidence thereof in the absence of manifest error. If such Lender makes the payment to the Agent required herein, the amount so paid shall constitute such Lender’s Rateable Portion of the Loan for purposes of this Agreement. The failure of any Lender to make its Rateable Portion of any Loan shall not relieve any other Lender of its obligation, if any, hereunder to make its Rateable Portion of such Loan on the Drawdown Date, Rollover Date or Conversion Date, as the case may be, but no Lender shall be responsible for the failure of any other Lender to make the Rateable Portion of any Loan to be made by such other Lender on the date of any Drawdown, Rollover or Conversion, as the case may be.

13.3 Remittance of Payments

          Except for amounts payable to the Agent for its own account, forthwith after receipt of any repayment pursuant hereto or payment of interest or fees pursuant to Article 5 or payment pursuant to Article 7, the Agent shall remit to each Lender its Rateable Portion of such payment; provided that, if the Agent, on the assumption that it will receive on any particular date a payment of principal, interest or fees hereunder, remits to a Lender its Rateable Portion of such payment and the Borrower fails to make such payment, each of the Lenders on receipt of such remittance from the Agent agrees to repay to the Agent forthwith on demand an amount equal to the remittance together with all reasonable costs and expenses incurred by the Agent in connection therewith and interest thereon at the rate and calculated in the manner applicable to the Loan in respect of which such payment is made, or, in the case of a remittance in respect of Bankers’ Acceptances, at the rate of interest applicable to Canadian Prime Rate Loans for each day from the date such amount is remitted to the Lenders without prejudice to any right such Lender may have against the Borrower. The exact amount of the repayment required to be made by the Lenders pursuant hereto shall be as set forth in a certificate delivered by the Agent to each Lender, which certificate shall be conclusive and binding for all purposes in the absence of manifest error.

13.4 Redistribution of Payment

          Each Lender agrees that:

(a)

if the Lender exercises any security against or right of counter-claim, set off or banker’s lien or similar right with respect to the property of the Borrower or if under any applicable bankruptcy, insolvency or other similar law it receives a secured claim and collateral for which it is, or is entitled to exercise any set-off against, a debt owed by it to the Borrower, the Lender shall apportion the amount thereof proportionately between:

	(i)		such Lender’s Rateable Portion of all outstanding Obligations owing by the Borrower (including the face amounts at maturity of Bankers’ Acceptances accepted by the Lenders), which amounts shall be applied in accordance with Section 13.4(b); and
	(ii)		amounts otherwise owed to such Lender by the Borrower,

provided that (i) any cash collateral account held by such Lender as collateral for a letter of credit or bankers’ acceptance (other than a Bankers’ Acceptance) issued or accepted by such Lender on behalf of the Borrower may be applied by such Lender to such amounts owed by the Borrower to such Lender pursuant

to such letter of credit or in respect of any such bankers’ acceptance without apportionment and (ii) these provisions do not apply to:

	(A)		a right or claim which arises or exists in respect of a loan or other debt in respect of which the relevant Lender holds a Lien which is a Permitted Encumbrance;
	(B)		cash collateral provided, or the exercise of rights of counterclaim, set-off or banker’s lien or similar rights, in respect of account positioning arrangements for the Borrower and its Subsidiaries provided by a Lender in the ordinary course of business or in respect of other cash management services provided by a Lender in the ordinary course of business;
	(C)		any reduction in amounts owing to the Borrower or a Subsidiary upon the termination of Hedging Instruments entered into with the relevant Lender or its Affiliates; or
	(D)		any payment to with a Lender is entitled as a result of any credit derivative or other form of credit protection obtained by such Lender;

	(b)		if, in the aforementioned circumstances, the Lender, through the exercise of a right, or the receipt of a secured claim described in Section 13.4(a) above or otherwise, receives payment of a proportion of the aggregate amount of Obligations due to it hereunder which is greater than the proportion received by any other Lender in respect of the aggregate Obligations due to the Lenders (having regard to the respective Rateable Portions of the Lenders), the Lender receiving such proportionately greater payment shall purchase, on a non-recourse basis at par, and make payment for a participation (which shall be deemed to have been done simultaneously with receipt of such payment) in the outstanding Loans of the other Lender or Lenders so that their respective receipts shall be pro rata to their respective Rateable Portions; provided, however, that if all or part of such proportionately greater payment received by such purchasing Lender shall be recovered by or on behalf of the Borrower or any trustee, liquidator, receiver or receiver-manager or person with analogous powers from the purchasing Lender, such purchase shall be rescinded and the purchase price paid for such participation shall be returned to the extent of such recovery, but without interest unless the purchasing Lender is required to pay interest on such amount, in which case each selling Lender shall reimburse the purchasing Lender pro rata in relation to the amounts received by it. Such Lender shall exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders entitled under this Section to share in the benefits of any recovery on such secured claims; and
	(c)		if the Lender does, or is required to do, any act or thing permitted by Section 13.4(a) or (b) above, it shall promptly provide full particulars thereof to the Agent.

13.5 Duties and Obligations

          Neither the Agent nor any of its directors, officers, agents or employees (and, for purposes hereof, the Agent shall be deemed to be contracting as agent and trustee for and on behalf of such persons) shall be liable to the Lenders for any action taken or omitted to be taken by it or them under or in connection with this Agreement except for its or their own gross negligence or willful misconduct. Without limiting the generality of the foregoing, the Agent:

(a)

may assume that there has been no assignment or transfer by any means by the Lenders of their rights hereunder, unless and until the Agent receives written notice of the assignment thereof from

			such Lender and the Agent receives from the assignee an executed Assignment Agreement providing, inter alia, that such assignee is bound hereby as it would have been if it had been an original Lender party hereto;
	(b)		may consult with legal counsel (including receiving the opinions of Borrower’s counsel and Lenders’ Counsel required hereunder), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts;
	(c)		shall incur no liability under or in respect of this Agreement by acting upon any notice, consent, certificate or other instrument or writing (which may be by telegram, cable, facsimile transmission, electronic mail or other electronic means of communication which may generate a written record thereof) believed by it to be genuine and signed or sent by the proper party or parties or by acting upon any representation or warranty of the Borrower made or deemed to be made hereunder;
	(d)		may assume that no Default or Event of Default has occurred and is continuing unless it has actual knowledge to the contrary;
	(e)		may rely as to any matters of fact which might reasonably be expected to be within the knowledge of any person upon a certificate signed by or on behalf of such person;
	(f)		shall not be bound to disclose to any other person any information relating to the Borrower, any of its Subsidiaries or any other person if such disclosure would or might in its opinion constitute a breach of any applicable law, be in default of the provisions hereof or be otherwise actionable at the suit of any other person; and
	(g)		may refrain from exercising any right, power or discretion vested in it which would or might in its reasonable opinion be contrary to any applicable law or any directive or otherwise render it liable to any person, and may do anything which is in its reasonable opinion necessary to comply with such applicable law.

Further, the Agent (i) does not make any warranty or representation to any Lender nor shall it be responsible to any Lender for the accuracy or completeness of the representations and warranties of the Borrower herein or the data made available to any of the Lenders in connection with the negotiation of this Agreement, or for any statements, warranties or representations (whether written or oral) made in or in connection with this Agreement; (ii) shall not have any duty to ascertain or to enquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement on the part of the Borrower or to inspect the property (including the books and records) of the Borrower or any of its Subsidiaries; and (iii) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any instrument or document furnished pursuant hereto.

13.6 Prompt Notice to the Lenders

          Notwithstanding any other provision herein, the Agent agrees to provide to the Lenders, with copies where appropriate, all information, notices and reports required to be given to the Agent by the Borrower, promptly upon receipt of same, excepting therefrom information and notices relating solely to the role of Agent hereunder.

13.7 Agent’s and Lenders’ Authorities

          With respect to its Commitment and the Drawdowns, Rollovers, Conversions and Loans made by it as a Lender, the Agent shall have the same rights and powers under this Agreement as any other Lender and may

exercise the same as though it were not the Agent. Subject to the express provisions hereof relating to the rights and obligations of the Agent and the Lenders in such capacities, the Agent and each Lender may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower and its Subsidiaries or any corporation or other entity owned or controlled by any of them and any person which may do business with any of them without any duties to account therefor to the Agent or the other Lenders and, in the case of the Agent, all as if it was not the Agent hereunder.

13.8 Lender Credit Decision

          It is understood and agreed by each Lender that it has itself been, and will continue to be, solely responsible for making its own independent appraisal of and investigations into the financial condition, creditworthiness, condition, affairs, status and nature of the Borrower and its Subsidiaries. Each Lender represents to the Agent that it is engaged in the business of making and evaluating the risks associated with commercial revolving or term loans, or both, to corporations similar to the Borrower, that it can bear the economic risks related to the transaction contemplated hereby, that it has had access to all information deemed necessary by it in making such decision (provided that this representation shall not impair its rights against the Borrower) and that it is entering into this Agreement in the ordinary course of its commercial lending business. Accordingly, each Lender confirms with the Agent that it has not relied, and will not hereafter rely, on the Agent (i) to check or enquire on its behalf into the adequacy, accuracy or completeness of any information provided by the Borrower or any other person under or in connection with this Agreement or the transactions herein contemplated (whether or not such information has been or is hereafter distributed to such Lender by the Agent), or (ii) to assess or keep under review on its behalf the financial condition, creditworthiness, condition, affairs, status or nature of the Borrower or any of its Subsidiaries. Each Lender acknowledges that a copy of this Agreement has been made available to it for review and each Lender acknowledges that it is satisfied with the form and substance of this Agreement. Each Lender hereby covenants and agrees that, subject to Section 13.4, it will not make any arrangements with the Borrower for the satisfaction of any Loans or other Obligations without the consent of all the other Lenders.

13.9 Indemnification of Agent

          The Lenders hereby agree to indemnify the Agent (to the extent not reimbursed by the Borrower), on a pro rata basis in accordance with their respective Commitment as a proportion of the aggregate of all outstanding Commitments, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Agent in any way relating to or arising out of this Agreement or any action taken or omitted by the Agent under or in respect of this Agreement in its capacity as Agent; provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs expenses or disbursements resulting from the Agent’s gross negligence or willful misconduct. If the Borrower subsequently repays all or a portion of such amounts to the Agent, the Agent shall reimburse the Lenders their pro rata shares (according to the amounts paid by them in respect thereof) of the amounts received from the Borrower. Without limiting the generality of the foregoing, each Lender agrees to reimburse the Agent promptly upon demand for its portion (determined as above) of any out-of-pocket expenses (including counsel fees) incurred by the Agent in connection with the preservation of any rights of the Agent or the Lenders under, or the enforcement of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that the Agent is not reimbursed for such expenses by the Borrower.

13.10 Successor Agent

          The Agent may, as hereinafter provided, resign at any time by giving 45 days’ prior written notice thereof to the Lenders and the Borrower. Upon any such resignation, the Lenders shall, after soliciting the view of the Borrower, have the right to appoint another Lender as a successor agent (the “Successor Agent”) who shall be acceptable to the Borrower, acting reasonably. If no Successor Agent shall have been so appointed by the Lenders

and shall have accepted such appointment within 30 days after the retiring Agent’s giving of notice of resignation, then the retiring Agent shall, on behalf of the Lenders, appoint a Successor Agent who shall be a Lender acceptable to the Borrower, acting reasonably. Upon the acceptance of any appointment as Agent hereunder by a Successor Agent, such Successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall thereupon be discharged from its further duties and obligations as Agent under this Agreement. After any retiring Agent’s resignation hereunder as Agent, the provisions of this Article shall continue to enure to its benefit as to any actions taken or omitted to be taken by it as Agent or in its capacity as Agent while it was Agent hereunder.

13.11 Taking and Enforcement of Remedies

          Each of the Lenders hereby acknowledges that, to the extent permitted by applicable law, the remedies provided hereunder to the Lenders are for the benefit of the Lenders collectively and acting together and not severally and further acknowledges that its rights hereunder are to be exercised not severally, but collectively by the Agent upon the decision of the Majority of the Lenders regardless of whether acceleration was made pursuant to Section 10.2. Notwithstanding any of the provisions contained herein, each of the Lenders hereby covenants and agrees that it shall not be entitled to individually take any action with respect to the Credit Facility, including, without limitation, any acceleration under Section 10.2, but that any such action shall be taken only by the Agent with the prior written agreement or instructions of the Majority of the Lenders; provided that, notwithstanding the foregoing, if (a) the Agent, having been adequately indemnified against costs and expenses of so doing by the Lenders, shall fail to carry out any such instructions of the Majority of the Lenders, any Lender may do so on behalf of all Lenders and shall, in so doing, be entitled to the benefit of all protections given the Agent hereunder or elsewhere, and (b) in the absence of instructions from the Majority of the Lenders and where in the sole opinion of the Agent the exigencies of the situation warrant such action, the Agent may without notice to or consent of the Lenders or any of them take such action on behalf of the Lenders as it deems appropriate or desirable in the interests of the Lenders. Each of the Lenders hereby further covenants and agrees that upon any such written consent being given by the Majority of the Lenders, or upon a Lender or the Agent taking action as aforesaid, it shall cooperate fully with the Lender or the Agent to the extent requested by the Lender or the Agent in the collective realization including, without limitation, and, if applicable, the appointment of a receiver, or receiver and manager to act for their collective benefit. Each Lender covenants and agrees to do all acts and things and to make, execute and deliver all agreements and other instruments, including, without limitation, any instruments necessary to effect any registrations, so as to fully carry out the intent and purpose of this Section; and each of the Lenders hereby covenants and agrees that, subject to Section 5.7, Section 13.4 and Section 9.2(a) it has not heretofore and shall not seek, take, accept or receive any security for any of the obligations and liabilities of the Borrower hereunder or under any other document, instrument, writing or agreement ancillary hereto and shall not enter into any agreement with any of the parties hereto or thereto relating in any manner whatsoever to the Credit Facility, unless all of the Lenders shall at the same time obtain the benefit of any such security or agreement.

          With respect to any enforcement, realization or the taking of any rights or remedies to enforce the rights of the Lenders hereunder, the Agent shall be a trustee for each Lender, and all monies received from time to time by the Agent in respect of the foregoing shall be held in trust and shall be trust assets within the meaning of applicable bankruptcy or insolvency legislation and shall be considered for the purposes of such legislation to be held separate and apart from the other assets of the Agent, and each Lender shall be entitled to their Rateable Portion of such monies. In its capacity as trustee, the Agent shall be obliged to exercise only the degree of care it would exercise in the conduct and management of its own business and in accordance with its usual practice concurrently employed or hereafter instituted for other substantial commercial loans.

13.12 Reliance Upon Agent

          The Borrower shall be entitled to rely upon any certificate, notice or other document or other advice, statement or instruction provided to it by the Agent pursuant to this Agreement, and the Borrower shall

generally be entitled to deal with the Agent with respect to matters under this Agreement which the Agent is authorized to deal with without any obligation whatsoever to satisfy itself as to the authority of the Agent to act on behalf of the Lenders and without any liability whatsoever to the Lenders for relying upon any certificate, notice or other document or other advice, statement or instruction provided to it by the Agent, notwithstanding any lack of authority of the Agent to provide the same.

13.13 No Liability of Agent

          The Agent shall have no responsibility or liability to the Borrower on account of the failure of any Lender to perform its obligations hereunder (unless such failure was caused, in whole or in part, by the Agent’s failure to observe or perform its obligations hereunder), or to any Lender on account of the failure of the Borrower or any Lender to perform its obligations hereunder.

13.14 Article for Benefit of Agent and Lenders

          The provisions of this Article 13 which relate to the rights and obligations of the Lenders to each other or to the rights and obligations between the Agent and the Lenders shall be for the exclusive benefit of the Agent and the Lenders, and, except to the extent provided in Sections 13.1, 13.2, 13.6, 13.10, 13.11, 13.12, 13.13 and this Section 13.14, the Borrower shall not have any rights or obligations thereunder or be entitled to rely for any purpose upon such provisions. Any Lender may waive in writing any right or rights which it may have against the Agent or the other Lenders hereunder without the consent of or notice to the Borrower.
